人们普遍认为，自闭症患者难以在语境中处理模棱两可的语言信息。为了调查这一说法，我们记录了24名患有自闭症谱系障碍的青少年和24名语言匹配的同龄人的眼动，因为他们监控了计算机显示器上与物体对应的口语句子，在目标单词之后，参与者更多地看着具有相同首音的竞争对手物体，而不是语音上无关的物体。然而，这种影响是由句子语境调节的，这样，如果语音竞争对手与前面的动词在语义上不一致，参与者就会较少地关注它。与预测相反的是，这两组受试者的眼球运动受到了相似的环境影响。相反，在这两组人中，语言技能相对较差的人受到句子上下文的影响较小。对自闭症的弱中枢一致性解释的含义进行了讨论。(C)2008爱思唯尔B.V.保留所有权利。
it is widely argued that people with autism have difficulty processing ambiguous linguistic information in context. To investigate this claim, we recorded the eye-movements of 24 adolescents with autism spectrum disorder and 24 language-matched peers as they monitored spoken sentences for words corresponding to objects on a computer display, Following a target word, participants looked more at a competitor object sharing the same onset than at phonologically unrelated objects. This effect was, however, mediated by the sentence context such that participants looked less at the phonological competitor if it was semantically incongruous with the preceding verb. Contrary to predictions, the two groups evidenced similar effects of context on eye-movements. Instead, across both groups, the effect of sentence context was reduced in individuals with relatively poor language skills. Implications for the weak central coherence account of autism are discussed. (c) 2008 Elsevier B.V. All rights reserved.
